So I changed my petcock because it seeped a bit and I wanted one with an on/off. Swapped it and it ran great until I went around the block and then it acted like it was flooding. There was a brass filter tube around the plastic tube that goes into the tank that I didn't use on the new one. I drained the fuel and swapped back to the old petcock with the brass filter tube and it did the same thing. I literally didn't do anything but take the fuel line off the old petcock, swap it and put it back on. It idles fine and revs on the stand but when trying to ride it bogs out and won't accelerate. ??
